🇬🇹 Guatemala · Las Verapaces
Laguna Lachuá is one of the most surprising and remote natural jewels in Guatemala: an almost perfectly circular lake of turquoise water, ringed by humid tropical rainforest, at the heart of Laguna Lachuá National Park in northwestern Alta Verapaz. Its rounded shape and crystalline color, due to its high mineral and sulfur content, give it an almost unreal look in the middle of the jungle.
Getting there takes effort —it's far from the usual tourist routes and to reach the shore you have to walk some 4 km along a jungle trail from the park entrance— but the reward is enormous: a serene, clean lake where you can swim, a setting of barely disturbed tropical forest, abundant wildlife (monkeys, birds, butterflies) and a silence that invites you to switch off completely. It's a destination for lovers of nature and quiet.
This guide covers the practical side of visiting Lachuá: how to get there from Cobán, what the access hike is like, what you can do at the lake, the overnight options inside the park (camping and rustic dorms) and the essential tips for a remote and safe experience. Lachuá is nature in its purest state, far from the noise.
Laguna Lachuá is a lake of karstic origin (possibly related to limestone dissolution or to an ancient impact, according to different hypotheses), circular in shape with turquoise waters rich in minerals. It was declared a National Park in 1976 to protect one of the last remnants of humid tropical rainforest in the region. The park is managed by CONAP with the participation of local Q'eqchi' communities and forms part of an important biodiversity corridor in northwestern Alta Verapaz.

Origins, formation and what the sources say.
Laguna Lachuá catches the eye above all for its shape: an almost perfect circle of turquoise water in the middle of the tropical rainforest of northwestern Alta Verapaz, in Guatemala. That remarkably regular geometry has fed different explanations of its geological origin. The most widely accepted hypothesis links it to karst processes: the region is formed of limestone that water dissolves over time, creating sinkholes and depressions; Lachuá would be a large flooded doline or sinkhole, a common phenomenon in limestone landscapes like those of the Yucatán peninsula and much of the Maya Lowlands.
The turquoise coloring and the characteristic sulfurous smell of the water are due to dissolved minerals and sulfur compounds, linked to the local geology and to underground springs. Its name also comes from that composition and from the Q'eqchi' language: 'Lachuá' is usually read as derived from Q'eqchi' expressions relating to 'smelly water' or 'fetid water', a reference precisely to that sulfur odor. Technicalities aside, the lake is a deep body of water, clean and notably transparent, set in one of the few well-preserved remnants of humid rainforest in the region.
Beyond the lake, the area protects one of the last great fragments of lowland humid tropical rainforest in north-central Guatemala, an ecosystem that has disappeared across much of the country through agricultural and cattle expansion. This forest shelters remarkable biodiversity: mammals such as howler and spider monkeys, pacas, peccaries and wild cats; a rich birdlife with toucans, parrots and water birds; reptiles, amphibians and varied aquatic life in the lake and the Lachuá river, linked to the Chixoy or Salinas river system.
Lachuá's ecological value is reinforced by its role as part of a biological corridor connecting different natural areas of northwestern Alta Verapaz, in a region under pressure from deforestation. Conserving this enclave is therefore especially important, and it's considered a site of great relevance for protecting lowland flora and fauna, as well as for regulating the water of the basin.
Official recognition of Lachuá's importance came in 1976, when the lake and its surrounding forest were declared a National Park, with the aim of protecting both the body of water and the woodland remnant around it. The creation of the park sought to halt the advance of the agricultural frontier and deforestation in an area of relatively recent settlement, where campesino and Q'eqchi' Indigenous communities had established themselves.
Over time, the management of the park, in the hands of CONAP (the National Council of Protected Areas), evolved toward a model of greater participation by the surrounding local communities, who take part in caring for the area and in the tourist services (guides, basic lodging, trail maintenance). This community-based conservation approach seeks to reconcile protection of the ecosystem with benefits for the Q'eqchi' populations living nearby, tying the survival of the forest to responsible tourism and to appreciation of the natural heritage.
The lake's name comes from Q'eqchi', the Maya language spoken by the communities who have lived in this region of northwestern Alta Verapaz since pre-Hispanic times. 'Lachuá' is usually translated as 'foul water' or 'smelly water', a direct reference to the characteristic sulfurous odor its waters give off from dissolved sulfur compounds, a result of the karst geology of the setting. Far from being a defect, that trait is part of the place's singular identity.
For the Q'eqchi' people, who have inhabited these tropical rainforest lowlands for centuries, the lake and its surroundings are not merely a natural resource but a space with its own place in their relationship with the territory. Subsistence agriculture, based on maize, beans and other crops, has historically coexisted with the preservation of large stretches of forest, in a region that until well into the 20th century remained under little demographic and agricultural settlement pressure compared with other parts of Guatemala.
The arrival of new waves of campesino settlement toward the middle of the 20th century, driven in part by the lack of land in other regions of the country, began to press on these forests, laying the groundwork for the later need to protect the area legally.
Since its designation as a National Park in 1976, Lachuá has faced the constant challenge of reconciling strict protection of the ecosystem with the needs of the campesino and Indigenous communities settled on its periphery. Pressure from the agricultural frontier, cattle ranching and, in more recent decades, crops such as African palm in some nearby areas of Alta Verapaz and neighboring Ixcán, have made the Lachuá forest one of the last well-preserved strongholds of lowland humid tropical forest in north-central Guatemala.
To sustain conservation, CONAP promoted a management model that brings in the neighboring communities as active players: training local guides, providing basic lodging and food services, and taking part in the upkeep of the trails and the visitor center. This approach seeks to make the forest worth more standing —through tourism and the environmental services it provides— than felled for agriculture or cattle.
Today, Lachuá receives a still modest number of visitors compared with other natural destinations in Guatemala, which has allowed much of its wild character to be preserved. That same remoteness, however, demands patience, self-sufficiency and an attitude of respect from the traveler toward a fragile ecosystem and toward the communities that care for it, ensuring that future generations can go on contemplating the 'mirror of the sky' in the middle of the jungle.
